Sometimes you're not visiting a place to engage deeply with humans, but to take in the natural landscape and the historic sites, or simply to exist for a short time somewhere that's not like home. Sometimes while travelling (especially while travelling!) you have limited time and need to have a quick bite and keep moving, because long meals and deep conversations are not your priority.
Sometimes it's ok to say "here's my brief impression of this place, and here are its highlights and its faults from my perspective" because at least that's expressing an opinion. I don't need another Instagrammer making the most vague statements about a foreign place, telling me how beautiful/resilient/spirited the people are despite their circumstances, and saying noting more concrete, because anything more specific will be met with offense that the traveller could never possibly understand the context of this people or that country, and is just a spoiled westerner.
The author will be describing interesting things about the place in a neutral or respectful tone for a line or five, and then suddenly switch to a sort of review-and-compare-mode, as if it were not a real place with 12 million people in it, but a product that just arrived in the post with this feature and that.
Or like a pokemon card, as I said, but for grown-ups. I have a Tunisia, it does xyz. It's good at this and bad at that. I mean that metaphor seriously, I think it really applies.
I mention the idea of putting in the extra effort to interact with locals - through volunteering, or whatever - not to make some comment about myself, or make some appeal to purity, but rather because it's a very good way to avoid turning travelling into stamp-collecting. It's a way of forcing yourself to see the subtlety and variety in a place.
The one assumption I felt myself to be making was that he reads Wikipedia, but that's hardly a heinous crime or anything. It was of no relevance to my point anyway.
Otherwise, regarding ranting - that's just, like, your opinion, man
The author decided to write an article about their experience and limited research, which opens them up to criticism.
